Relative expression of <i>Erbb2</i> and <i>Mycn</i> in the HH-16 cl.2/1 and HH-16.cl.4 cell lines.

<p>Expression results were obtained by reverse transcription quantitative real time PCR, normalized with the reference genes beta-actin and GAPDH and compared with a control sample. Data is presented as mean corresponding to fold change relative to the control sample (p<0.05). Error bars represent ±SD.
